BAR SUPPORT AND SPACER.-

Application fiied February 12, 1927. Serial No. 167,686.

This invention relates to reinforcing systems for concrete constructionwork.

The main objects of this invention are to provide improved means forspacingthe reinforcing bars; to provide improved .meansfor supportingsaid spacing means; and to provide an improved bar support and spacerwhereby the reinforcingbars may be supported in rows disposed indifi'erent ill) planes. 1

An illustrative embodiment of this invention is shown in theaccompanying drawing wherein 1 Figure 1 is a vertical section of a moldshowing a reinforcing system to which the invention is applied.

Fig. 2 is a perspective of one of the im proved devices.

Fig. 3 is a side elevation of the spacing rod. 1 a

Fig. 4: is aside elevation of one of the supporting legs. V

In the form shown, the reinforcing system involves the use of aplurality of reinforcing bars 1, disposed horizontally above a falsework2 and supported in rows in substantially parallel spaced relation by theim proved bar supports and spacers.

The support and spacer is preferably made of wire of comparatively heavygauge which possesses the necessary rigidity and which may be bent tothe desired form.

In the specific form herein illustrated,- the devicecomprises a rod 3,having a plurality oi crooks formed at regular intervals along itslength to provide substantially U-shaped seats 4-, for supporting thereinforcing bars 1.. The intermediate portions of the rod 3 providespacers 5 for spacing the bars 1 laterally. The seats 4 and spacers 5are disposed in a single vertical plane,

Secured to each of the seats 4, is a pair of supporting legs 6, arrangedat respectively opposite ends of the seat and on re spectively oppositesides of the rod 3. The legs 6 are preferably Lshaped, so as to provideupright portions 7, disposed substantially in the plane of the seats 4,and feet 8 extending outwardly therefrom. The feet of each pair of legsextend in respectively opposite directions to stabilize the structure.The legs 6 are disposed-preferably in substantially parallel planes atright angles to the plane of the spacing rod 3. In the form shown,the-upright portions 7 of the legs 6 project above the seats 4 toprovide fingers, which are adapted to be bent over. the reinforcing bars1 for securing them to the supports. 7 s

In order to permit thedevices to be supported oneabove the other forsupporting the reinforcing bars in rows, thelegs ofthe spacers above thebottom row are provided with additional supporting means to enable themto rest upon the next succeeding lower bars.

As shown in Figs. 1 and 2, the additional supporting means comprises apair of rods 9'secured to the feet 8 and disposed substantially parallelto the spacers The legs 6 are secured to the rods 8 and 9 preferably byspot welding.

In operation, the lower devices are placed on the falsework 2 and afterthe first row of bars has been placed thereon, the fingers 7 are bentover the bars to secure the latter against displacement. Other devicesare then placed above the bars with the rods 9 resting directly on thelower bars. lVith this improved construction and arrangement of parts, areinforcing system may be constructed involving any number of rows ofbars.

Although but one specific embodiment of this invention has been shownand described, it will be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as defined by the following claims.

I claim:

1. A device of the class described com prising a spacing rod bent toform a pinrality of substantially U-shaped seats disposed in one planefor supporting reinforcing bars in spaced relation to one another, and apair of L-shaped legs secured to each of said seats and located insubstantially parallel planes disposed at right angles to said oneplane, one portion of each of said legsbeing located substantially inthe plane of said seats and the other portion thereof providing a foot,certain of said first mentioned portions extending beyond said seats toform fingers adapted to be bent around the reinforcing bars. a

2. A device of the class described comprising a spacing rod bentto forma plurality of substantially U-shaped seats d-isposed in one plane forsupporting reinforcing bars in spaced relation .to one another, and apair of L-.sl1aped legs secured to each of said seats on respectivelyopposite sides of said rod and located in substantially parallel planesdisposed at right angles to said one plane, one portion of each of saidlegs being located substantially in the plane of said seats and theother portion thereof providing a foot, certain of said first mentionedportions extending beyond said seats to form fingers adapted to be bentaround the reinforcing bars.

3. A device of'the class described comprising a rod bent at intervals toform a plurality of substantially U-shaped seats disosed in one planefor supporting reinforcing bars, the intermediate portions of said rodserving to space the bars, a pair of L-shaped legs secured to each ofsaid seats at respectively opposite ends thereof and located insubstantially parallel planes disposed at right angles to said oneplane, portions of said legs providing feet, and a pair of other rodssecured to said feet on respectively opposite sides of said one planeand disposed substantially parallel to said intermediate spacingportions of said first mentioned rod.
